What I would like to see is an adapted wand with say 5 loading cylinders running the length of the normal loading area. This idea is similar to the original small loading area plan in a way.
When vaporizing your goal is to maximise the surface area of your products that are in contact with the heat, i.e. in the direct airflow from the element. Currently people seem to favour packing, but I dont agree.
Rather, I suggest you finely ground and press before loading. Now what you have will be a number of flat pieces of condensed material, therein lie two benefits. First, condensed material always produces a higher vapour yield. Second, flat lengths of material can be formed into shapes of great surface area (consider concentric cylinders), this is key.
Ideally, i would like to see, for the sake of argument, five small cylinders to be ideally filled with pressed sift, pressed in such a way tat it coats the walls of the chambers. Now, surface area=5.pi.d.l where d is the diameter of each cylinder and l the length. All pretty simple, pi.d is the circumference of a circle, multiply by the length to bring it into 3 dimensions finally there are five chambers.
Your input is encouraged, if you want I will supply pictures. I hope i dont come across as another armchair mathematician stoner, i do hold a degree in the subject, though my interests were in algebra. If my ideas are off I will be slightly embarrassed.
